Rule 23 Predominance Requires State-by-State Erie Predictions—Unsettled State Law Alone Cannot Defeat a Multistate Class

Case: Generation Changers Church v. Church Mutual Ins. Co. (6th Cir. Feb. 23, 2026)
Court: United States Court of Appeals for the Sixth Circuit
Key Holding (new practical rule): In evaluating Rule 23(b)(3) predominance for multistate state-law classes, a district court must actually perform (and explain) Erie predictions for the relevant states using available sources (including intermediate state decisions, federal decisions, and sister-circuit authority). A court may not deny certification for “unsettled” state law merely to avoid that analysis—though a plaintiff still bears the burden to supply meaningful state-law proof (as Vermont illustrates).

1. Introduction

This appeal arises from an insurance dispute over how to calculate actual cash value (ACV) after a tornado damaged two Tennessee properties owned by Generation Changers Church (GCC). GCC’s insurer, Church Mutual Insurance Company (Church Mutual), paid the claim but allegedly reduced the ACV by depreciating not only materials but also “non-material” items—most importantly labor-related components (e.g., overhead, profit, removal, equipment). GCC contends the policy did not clearly authorize depreciation of those non-material costs.

GCC sued for breach of contract and declaratory relief and sought to proceed as a multistate class action on behalf of insureds in ten states (Tennessee plus nine others). The district court certified a class only for Arizona, California, Illinois, and Tennessee, and refused certification for Kentucky, Ohio, Missouri, Mississippi, Texas, and Vermont. The district court’s primary reason was that law in those six states was “unsettled,” requiring individualized state-by-state inquiries that would make the class “prohibitively unwieldy.”

On appeal, two threshold questions framed the dispute:

  • Standing: Does a Tennessee plaintiff have Article III standing to represent class members whose claims arise under other states’ laws?
  • Predominance / Erie: When state law is unsettled, may a court deny a multistate class because it would have to do “fresh” Erie predictions, or must it actually do that work (based on available sources) before rejecting predominance?

2. Summary of the Opinion

The Sixth Circuit (Judge Griffin) held:

  • No standing bar: GCC has Article III standing. The alleged injuries across the putative class (reduced ACV due to depreciation of non-material costs under materially identical policies and the same depreciation software) are sufficiently aligned with GCC’s injury.
  • Erie analysis required for five states: The district court abused its discretion by refusing to conduct any meaningful Erie analysis for Kentucky, Ohio, Missouri, Mississippi, and Texas and by discounting binding and persuasive authorities without explanation.
  • Vermont treated differently: The district court did not abuse its discretion in denying certification as to Vermont because GCC relied solely on a non-binding regulatory bulletin, insufficient to meet its burden under Rule 23(b)(3).

The court therefore vacated in part the class-certification order and remanded for the district court to conduct Erie predictions for Kentucky, Ohio, Missouri, Mississippi, and Texas as part of the predominance inquiry.

3. Analysis

3.1. Precedents Cited (and how they shaped the decision)

A. Standing doctrine and the “standing vs. class certification” divide

  • Lujan v. Defs. of Wildlife and TransUnion LLC v. Ramirez: These cases supplied the baseline Article III framework—injury, causation, redressability—and the principle that standing is “not dispensed in gross.” The Sixth Circuit used them to confirm GCC must have standing for the claims it presses, but also to focus standing on concrete injury rather than on ultimately applicable state law.
  • Wal-Mart Stores, Inc. v. Dukes and Califano v. Yamasaki: Cited to situate class actions as an exception to individualized litigation, and to distinguish Article III questions from Rule 23 questions.
  • Rosen v. Tenn. Comm'r of Fin. & Admin., Warth v. Seldin, and Fox v. Saginaw County: These authorities emphasize that a class representative cannot create standing solely from absent class members’ injuries, especially where the defendant did not harm the plaintiff. The Sixth Circuit invoked them to show what would defeat standing—then explained why GCC’s case does not fit that scenario.
  • Gratz v. Bollinger: Used to identify the unresolved question whether differences between the named plaintiff’s claim and class members’ claims are a matter of Article III standing or Rule 23 propriety.
  • Speerly v. Gen. Motors, LLC (en banc) (Thapar, J., concurring): The court relied heavily on the concurrence’s taxonomy of the “standing approach” versus the “class certification approach,” but expressly declined to choose between them because GCC prevails under either.
  • Blum v. Yaretsky: Under the “standing approach,” Blum illustrates that plaintiffs cannot challenge conduct “sufficiently different” from what they experienced. The Sixth Circuit used Blum as the template and concluded GCC’s injury is the same kind of injury as the class’s injury (same alleged depreciation practice, same policy forms, same software).
  • Fallick v. Nationwide Mut. Ins. Co.: Cited in describing the “class certification approach,” under which once the named plaintiff has standing for its own injury, representational questions move into Rule 23 analysis.
  • Steel Co. v. Citizens for a Better Env't, Roberts v. Hamer, and Davis v. Passman: These cases grounded the court’s insistence on separating Article III standing (injury-based jurisdiction) from “statutory standing” or cause-of-action/merits questions. This was central to rejecting Church Mutual’s argument that GCC lacks standing simply because other states’ laws govern other class members’ claims.
  • Mayor of Balt. v. Actelion Pharms. Ltd. and Morrison v. YTB Int'l, Inc.: These reinforced the concept that the “choice of law” or whether plaintiffs can invoke other states’ statutes typically goes to merits/Rule 23 manageability rather than constitutional standing.

B. Rule 23(b)(3) predominance and the obligation to do Erie work

  • Amchem Prods., Inc. v. Windsor: Provided the high-level framework for Rule 23(b) categories and underlined the seriousness of certifying a class.
  • Tyson Foods, Inc. v. Bouaphakeo and Fox v. Saginaw County: Supplied the qualitative predominance methodology—“add up” common versus individualized issues and decide which side predominates, recognizing that some individual issues (e.g., damages) do not necessarily defeat certification.
  • Wal-Mart Stores, Inc. v. Dukes: Reappears as the source of the requirement that plaintiffs “prove” Rule 23 elements with “significant proof” and that district courts conduct a “rigorous” analysis that “probe[s] behind the pleadings.”
  • In re Ford Motor Co. and Speerly v. Gen. Motors, LLC: Established the abuse-of-discretion review standard and the circumstances that constitute legal error in certification decisions.

C. Erie prediction sources and deference rules

  • Erie R. Co. v. Thompkins: The foundation: federal courts apply state substantive law and must predict it where unsettled.
  • Savedoff v. Access Grp., Inc. and Kepley v. Lanz: Used to restate the two-step Erie method: follow the state’s highest court; if it has not spoken, make an “educated guess” as to how it would rule.
  • Meridian Mut. Ins. Co. v. Kellman: Critical to the appellate reversal: it lists legitimate tools for Erie prediction (lower-court state decisions, other federal decisions, restatements, commentary, and majority rules) and requires federal courts not to disregard intermediate appellate decisions absent persuasive evidence the state high court would disagree.
  • Ziegler v. IBP Hog Mkt., Inc.: Reinforced that intermediate appellate state decisions matter “regardless of whether ... published or unpublished.”
  • In re Dow Corning Corp.: Provided the principle that sister-circuit interpretations of states within their geographic footprint (here, Fifth Circuit on Mississippi) are “especially persuasive.”
  • Blaine Constr. Corp. v. Ins. Co. of N. Am.: Used to emphasize that district courts must follow binding circuit Erie predictions unless there is persuasive evidence that the state’s highest court would decide otherwise.
  • Hicks ex rel. Feiock v. Feiock: A Supreme Court statement that intermediate state appellate decisions are “a datum for ascertaining state law” not to be disregarded absent persuasive reasons. This supported the Sixth Circuit’s critique of the district court’s unexplained discounting of Missouri intermediate authority.
  • Cole v. Gen. Motors Corp. and Sacred Heart Health Sys., Inc. v. Humana Mil. Healthcare Servs., Inc.: These framed the allocation of labor: parties must supply authorities, but courts must decide even difficult questions rather than avoid them.

D. The ACV/labor-depreciation line of cases highlighted by the court

  • Hicks v. State Farm Fire & Casualty Co. (Hicks I) and Hicks v. State Farm Fire & Casualty Co. (Hicks II): Treated by the Sixth Circuit as binding circuit precedent (as of the district court’s decision) making Kentucky Erie predictions about labor depreciation—thus the district court could not dismiss Kentucky as “unsettled” without explaining why it could depart from Hicks.
  • Perry v. Allstate Indemnity Co. and Cranfield v. State Farm Fire & Casualty Co.: Similarly treated as controlling Erie predictions for Ohio, making the district court’s refusal to engage on Ohio law an abuse of discretion.
  • Mitchell v. State Farm Fire & Casualty Co.: A Fifth Circuit decision on Mississippi law holding “ACV” ambiguous in the relevant context. The Sixth Circuit emphasized the district court should have weighed this sort of sister-circuit authority rather than label Mississippi “unsettled” and stop.
  • Sims v. Allstate Fire & Cas. Ins. Co. and RSUI Indem. Co. v. The Lynd Co.: These were part of the Texas Erie discussion. Sims applied Mitchell’s reasoning by analogy, and RSUI supplied the Texas canon that ambiguities are construed against insurers—supporting the proposition that Texas might bar non-material depreciation absent clear policy language.

E. Vermont-specific authority

  • Vt. Ins. Bulletin No. 184 (May 1, 2015): GCC’s sole cited Vermont source; the Sixth Circuit agreed it was too thin to carry the Rule 23 burden.
  • Vt. Ins. Bulletin No. 174: Cited to show Vermont bulletins “establish neither binding norms nor finally determine issues or rights,” undercutting reliance on Bulletin 184.
  • Vt. Stat. Ann. tit. 8, § 4724(9)(F): The statute referenced by the bulletin, but it “says nothing about the depreciation of non-material costs,” leaving the bulletin as an advisory gloss without decisive content.

3.2. Legal Reasoning

A. Standing: the court refuses to constitutionalize choice-of-law disputes

Church Mutual’s principal jurisdictional theory was that GCC, a Tennessee entity harmed in Tennessee, lacks standing to pursue claims “under” other states’ laws. The Sixth Circuit rejected that framing as conflating two different questions:

  • Article III standing asks whether GCC suffered a concrete injury caused by Church Mutual and redressable by the court.
  • Whether GCC can invoke other states’ laws is a merits/choice-of-law/Rule 23 problem (often described as “statutory standing” or cause-of-action scope), not a constitutional injury problem.

Under the “standing approach,” the Sixth Circuit analogized to Blum v. Yaretsky and asked whether class members’ harms are a “close match” to GCC’s harm. The answer was yes because the alleged injury is operationally the same across states: Church Mutual allegedly used materially identical policy forms and the same software-driven practice that depreciated non-material costs, producing systematically reduced ACV payments. That unity of alleged conduct and injury prevents the case from becoming the kind of “different conduct” standing problem described in Blum.

Under the “class certification approach,” standing ends once GCC shows its own injury; representational fit is analyzed under Rule 23. Because GCC plainly has standing to sue for underpayment, the Article III debate could not bar the multistate class at the threshold.

B. Predominance and Erie: a court cannot avoid prediction work by calling state law “unsettled”

The opinion’s core operational rule is about judicial responsibility in multistate class certification. The district court effectively said: because several states lack state-supreme-court or statutory clarity on labor/non-material depreciation, the court would have to do “unique, state-by-state” work; therefore predominance fails and the ten-state class is “unwieldy.”

The Sixth Circuit deemed that a misapplication of Rule 23(b)(3) and Erie principles. Unsettled state law does not permit abstention from decision-making. Instead, Erie requires federal courts to predict state law using the full range of permissible sources. The appellate court’s critique had three recurring themes:

  • Binding circuit Erie predictions bind district courts unless persuasive evidence suggests the state’s highest court would rule differently. Thus, the district court erred by brushing aside Hicks v. State Farm Fire & Casualty Co. (Hicks II) (Kentucky) and Perry v. Allstate Indemnity Co. (Ohio) without explaining why they were not controlling.
  • Persuasive sources must be weighed, not ignored. The district court had already performed an Erie analysis for Texas at the pleadings stage and found it strongly favored GCC; it then failed to reconcile that conclusion with its later predominance analysis. The Sixth Circuit treated that inconsistency as a failure of the “rigorous” Rule 23 inquiry.
  • Intermediate state appellate decisions are “data” for state law and may not be discounted without reason. The district court’s unexplained dismissal of Missouri intermediate authority conflicted with Meridian Mut. Ins. Co. v. Kellman and Hicks ex rel. Feiock v. Feiock.

C. Vermont: the burden of proof still matters

The Sixth Circuit’s partial affirmance shows the decision is not “pro-certification at all costs.” Rule 23(b)(3) places the burden on plaintiffs to supply “significant proof” that common issues predominate—including proof about the content of state law where relevant.

For Vermont, GCC offered only Vt. Ins. Bulletin No. 184 (May 1, 2015), which the district court found non-binding in light of Vt. Ins. Bulletin No. 174, and which interpreted a statute (Vt. Stat. Ann. tit. 8, § 4724(9)(F)) that did not directly answer the labor-depreciation question. On that record, the Sixth Circuit held it was within the district court’s discretion to find Vermont insufficiently established for predominance purposes.

3.3. Impact

A. Practical consequences for multistate class actions in the Sixth Circuit

The opinion significantly constrains a common manageability move in multistate class certification: denying predominance because state law is “unsettled” and therefore “unwieldy.” After this decision, district courts must:

  • Perform and explain Erie predictions for each contested state whose law bears on predominance, using the recognized sources listed in Meridian Mut. Ins. Co. v. Kellman.
  • Follow binding circuit Erie predictions (e.g., Hicks v. State Farm Fire & Casualty Co. (Hicks II), Perry v. Allstate Indemnity Co.) unless they identify persuasive evidence the state’s highest court would disagree.
  • Reconcile intra-opinion Erie determinations (e.g., a Texas prediction used to deny judgment on the pleadings) with later certification analysis, rather than treating predictions as too uncertain to count.

B. Standing doctrine: limits on “state-law standing” attacks

Defendants frequently attempt to repackage choice-of-law and cause-of-action disputes as Article III defects. This opinion reinforces that:

  • A named plaintiff with a concrete injury from a uniform practice generally is not defeated on standing grounds merely because different state laws may apply to different class members.
  • The sharper battleground is Rule 23—commonality, typicality, predominance, and manageability—rather than constitutional jurisdiction.

C. Insurance litigation: ACV depreciation of labor/non-materials

While the Sixth Circuit did not decide the substantive ACV question for each state, the opinion strengthens plaintiffs’ ability to pursue multistate theories where:

  • policy language is uniform or materially identical,
  • the depreciation methodology is standardized (e.g., the same software), and
  • state-law differences can be predicted and grouped using conventional Erie tools.

At the same time, the Vermont holding signals that plaintiffs must present real state-law materials—bulletins and advisory guidance alone may not suffice.

4. Complex Concepts Simplified

  • Actual Cash Value (ACV): A common property-insurance measure roughly intended to pay the value of the damaged property at the time of loss. Here, Church Mutual calculated ACV as replacement/repair cost minus depreciation.
  • Depreciation of “non-material” costs (including labor): A contested practice. Materials (like shingles) obviously wear out; labor (the act of installing shingles) does not “wear out” in the same way. Whether an insurer may depreciate labor/non-material components depends heavily on policy language and state interpretive rules.
  • Erie analysis / Erie prediction: When state law governs and the state’s highest court has not answered a question, a federal court must predict how that court would rule, using intermediate state decisions, persuasive federal decisions, restatements, commentary, and majority rules.
  • Rule 23(b)(3) “predominance”: A class may be certified only if common questions outweigh individualized ones. It is not enough that common issues exist; they must be the main drivers of liability resolution.
  • Article III standing vs “statutory standing”: Article III standing is constitutional (injury, causation, redressability). “Statutory standing” is a merits question about whether a particular law provides a cause of action to this plaintiff. The Sixth Circuit warns against confusing the two.

5. Conclusion

Generation Changers Church v. Church Mutual Ins. Co. establishes a clear procedural expectation for multistate class certification in federal court: when state-law variation matters to predominance, district courts must do the Erie work—carefully, state by state, and with reasoned engagement with binding and persuasive authorities. “Unsettled” law is not a shortcut to denial where predictive tools exist and have been presented.

At the same time, the opinion preserves a meaningful plaintiff burden: where the proponent offers only thin, non-binding guidance (as with Vermont’s bulletin), a court may find predominance unmet. The combined effect is a more disciplined—and more transparent—approach to multistate Rule 23(b)(3) certification in state-law insurance disputes.
